These tables incorporate only the most common host crystals; many Other individuals exist, which can be considerably less commonly applied.
Listed here you are able to post concerns and opinions. So far as they get recognized with the author, they're going to appear earlier mentioned this paragraph together with the author’s respond to. The author will make a decision on acceptance dependant on selected criteria. Basically, The problem need to be of adequately wide desire.
Laser crystals are optical crystals �?typically one crystals (monocrystalline optical elements) �?which happen to be applied as achieve media for stable-condition lasers. Generally, they are doped with both trivalent rare earth ions or changeover metal ions.
激光晶体（laser crystal），可将外界提供的能量通过光学谐振腔转化为在空间和时间上相干的具有高度平行性和单色性激光的晶体材料。是晶体激光器的工作物质。
Which geometry, dopant and doping focus of the acquire medium are most advantageous depend upon a number of components. The accessible pump source (form of laser diode or lamp) as well as envisaged pumping arrangement are important elements, but the material itself also has some influence. As an example, titanium–sapphire lasers must be pumped with significant intensities, for which the form of the transversely cooled rod, operated with comparatively modest pump and laser beam diameter, is a lot more correct than e.
晶体的光学质量对激光器的有效运行至关重要。晶体中的缺陷或杂质可能导致光散射、吸收甚至损坏晶体。高光学质量确保了稳定和高质量的激光束。
激光晶体的损伤阈值与其能承受的最大光强有关，而不会遭受物理或结构损伤。高损伤阈值对于确保高功率激光应用的耐久性和长寿命至关重要。
探索激光晶体的领域，可以让我们看到科学和技术相结合的奇迹，为我们带来了令人难以置信的进步。这些激光晶体，每一种都在组成和特性上独具匠心，是推动现代世界众多应用的动力。
Several laser crystal elements are actually shown wherever some saturable absorber substance is incorporated for passive Q switching of the laser.
量子效率是发射光子数量与吸收光子数量的比率。高量子效率表明更大部分吸收能量被转化为激光光束，有助于提高激光的整体效率。

In 2017, we produced the world’s biggest Ti∶sapphire crystal (Φ235 mm), which supported The ten PW laser output of Shanghai Superintense Ultrafast Laser Facility. The event of Yb and Tm doped GdScO3 laser crystals with exceptionally vast emission spectra drives the development of laser diode pumped ultrafast reliable-condition lasers. With the increase in pulse Strength, peak ability, and repetition fee of reliable-state lasers, laser crystals will develop towards more substantial measurements, greater crystal quality, and controllable important functionality.
With That idea, a person does not need to have a further saturable absorber crystal, in more info order that just one may possibly make extra compact Q-switched laser setups with decreased internal parasitic losses. Having said that, unwanted Unwanted effects may additionally occur, for example getting unwanted valence states of your concerned ions or energy transfers.
